Another option that worked for a radeon user I was helping, was to set up the video chip in mergedfb mode initally with crt1 forced on or with the monitor attached. then use xrandr to resize the frame buffer on the fly. so if you have two 1024x768 heads set up the initial framebuffer as 2048x768 then use xrandr to resize to 1024x768. if you plug in the monitor rerun xrandr and change back to 2048x768. this only works in mergedfb mode and may not work on sis (I don't know that any one has tried it). Also you must start with a 2048x768 frambuffer. xrandr cannot resize up if you start out with a 1024x768 framebuffer. while this may work, this case was not taken into account when xrandr or mergedfb were written so YMMV.
